...Y. Shorrab; J.J. Blecher; R.S. Lillard This study aimed to determine the optimal heat treatment and build orientation to minimize the susceptibility of additively manufactured (AM) Alloy 625 to crevice corrosion. To accomplish this, metal-to-metal and acrylic-to-metal remote crevice assembly (RCA...

... in tropical and in temperate seawaters in heated conditions. Above 37°C, the biofilm activity was much more pronounced in tropical seawater compared to Atlantic Ocean sites, leading to much higher localized corrosion risk. Crevice corrosion of eight high-grades passive alloys was also studied with the use...

... measurements in deaerated environment, by means of continuous N₂ injection. The results obtained with the syringe cells, in both conditions (aerated and deaerated), were reproducible and free of crevice corrosion because the cell configuration does not allow obtaining this condition. The proposed...

...Abinaya Kamaraj; Johann Wilhelm Erning The susceptibility of Type 304 stainless steel (SS) to crevice corrosion upon contacting with electrochemically active fluids was investigated using exposure tests and stepwise potentiostatic polarization. Crevice materials made of 304 SS and polyether ether...

... humidity were investigated. Shallow and deep corrosion sites with filiform corrosion along with stress corrosion cracking (SCC) were formed beneath the salt-laden droplets, and the potential role of hydrogen embrittlement (HE) and crevice corrosion in damage evolution elucidated.
